Maybe you're getting it after all.
Nobody is perfect but anyone who trusts in Christ, who is IN Christ, has been declared righteous. We have been clothed in His righteousness because our lives are hidden with Christ in God.
Colossians 3:3 For you have died, and your life is hidden with Christ in God.
God does not count our sin against us, even though He does have the right to if He chooses. But he chose not to for those who by faith accept the work of Christ on the cross for their sins.
It's a legal pardon. Sure God knows we sin, but has chosen to not count our sins against us for Christ's sake.
Romans 4:1-10 1What then shall we say was gained by Abraham, our forefather according to the flesh? 2For if Abraham was justified by works, he has something to boast about, but not before God. 3For what does the Scripture say? "Abraham believed God, and it was counted to him as righteousness." 4Now to the one who works, his wages are not counted as a gift but as his due.
5And to the one who does not work but believes in him who justifies the ungodly, his faith is counted as righteousness, 6just as David also speaks of the blessing of the one to whom God counts righteousness apart from works: 7 "Blessed are those whose lawless deeds are forgiven, and whose sins are covered; 8blessed is the man against whom the Lord will not count his sin."
9Is this blessing then only for the circumcised, or also for the uncircumcised? We say that faith was counted to Abraham as righteousness.
If you sin, you are not perfect. Only God is perfect.
God does not count our sin against us, even though He does have the right to if He chooses. But he chose not to for those who by faith accept the work of Christ on the cross for their sins.
John 14: 21 Whoever has my commandments and observes them is the one who loves me. And whoever loves me will be loved by my Father, and I will love him and reveal myself to him.”o 22Judas, not the Iscariot,* said to him, “Master, [then] what happened that you will reveal yourself to us and not to the world?”p 23Jesus answered and said to him, “Whoever loves me will keep my word, and my Father will love him, and we will come to him and make our dwelling with him.q 24Whoever does not love me does not keep my words; yet the word you hear is not mine but that of the Father who sent me.
